Twelve cubical map presets are included with SOFTBOX (HDRI) for TurboCAD to get you started and to illustrate just a few of the lighting possibilities available to you with SOFTBOX (HDRI). For consistency, the images shown below were all rendered from the Isometric_SW view in TurboCAD. To achieve the same lighting effects when experimenting with the cubical map presets, you'll want to use the Isometric_SW view as well. The included Quality Plus luminance preset was used as the only light source in each of the thumbnail images to illustrate how simply changing the configuration of a cubical map will affect your renderings.

 

To apply a cubical map to your render scene in TurboCAD, bring up the SOFTBOX (HDRI) category in the Environments Palette and double click on one of the available presets. You may also right-click on a thumbnail and choose "Set Environment". See Applying a Render Scene Environment

	Broad Lighting Broad lighting is a term used in photography to describe lighting that is positioned to create a broad or wide highlight across the subject. The lighting in this image comes from two rectangular softboxes assigned to one side of the cubical map. This type of lighting can be useful for drawing attention to a certain feature on the subject.
	Broad Lighting Plus Fill This example uses the same broad lighting setup as above but with the addition of some fill light on the other side of the pot. The fill is provided by a single rectangular softbox with a -2 EV setting. By adding a fill light the contrast is reduced but a nice shading effect remains. Shading is an important factor in revealing shape, depth and contour in your renderings.
	Midnight The midnight example consists of a single octagonal softbox with a cool color tone assigned to the top of the cubical map. This illustrates how easy it is to create a dramatic mood in your renderings by taking advantage of the smooth shading and diffuse illumination provided by Image Based Lighting.
	Product Illustration In this example all sides of the cubical map are contributing to the scene's illumination. This type of lighting is used to help push back shadows and to bring all parts of a subject into good light. As the title states, this type of lighting is great for product and design renderings.
	Rim Lighting Rim lighting is a technique used by photographers to help separate a dark subject from a dark background. This is done by positioning lights behind the subject so that light spills around the edges just slightly. Here, with no fill light illuminating the front of the pot, the effect is quite dramatic.
	Rim Lighting Plus Fill By adding some fill light to the front of the pot we bring more of the pot into view and the scene becomes less dramatic.
	Short Lighting Short light is a term used in photography to describe lighting that is positioned such that it creates a short or narrow highlight on the subject. The lighting in this image comes from two rectangular softboxes that are mostly behind the right side of the pot acting as kickers . Kickers are typically used to add an extra highlight to a portion of the subject. Then, to bring some softer light around the front a bit, two more rectangular softboxes at -2 EV were added to the right-front side of the pot.
	Short Lighting Plus Fill This example uses the same short lighting setup as above but with the addition of some fill light on the other side of the pot with a -2EV setting. Adding a fill light to this setup reduces the overall contrast and transfers some emphasis to the rest of the subject. As mentioned above shading is an important factor in revealing shape, depth and contour in your renderings.
	Complex Reflection When rendering subjects with reflective surfaces you not only see the shading and shadow effects of light on the subject, you see the environment as well. This is one of the greatest advantages of using IBL. When using regular luminance or standard lights you'll see bright spots in reflective surfaces that reveal light source locations. Using IBL however, you'll see true to life reflections with shape and controllable exposure. In this example an array of strip softboxes surrounds the pot with a single square softbox assigned to the top position of the cubical map.
	Simple Reflection I This example of simple reflection uses a lightbox setup similar to what you would use for product illustration. The difference is that all but two of the positions on the cubical map have images with a setting of -3EV assigned to them. The advantage is that we get to add some illumination to the entire pot while maintaining a level of contrast to the main lighting.
	Simple Reflection II This example is similar the one above but with only one position of the cubical map at full brightness (0EV). That position contains three strip or narrow style softboxes. The top position was also left black on this example to add some interest to the reflection.
	Stark Reflection This example uses a single umbrella HDRI located at the top position of the cubical map. All other positions are left black to really bring in the contrast. Because the lighting is coming straight down the floor receives a good amount of illumination and becomes a big part of the reflection taking place on the pot. The benefit being that the shape of the pot is well defined by just a single light.
